The Schedule referred to in these Letters Patent aud making part of thesame. 1

To all whom it ma/ afconce/m:

Be it known that I, W. C. G. Ensnmn, of Nether Kinnedder, Dunfermline,Fifeshire, in Scotland, have invented a new and useful Improvement in.Coffee-- Pots; and I do hereby declare .that the following is 'a full,clear, and exact description thereof', which will enable others skilledin the art to make and use the' same, reference being had totheaccompanying drawings, forming part of this specification. i

This invention relates to improvements in coffee pots, designed toprovide a better arrangement forextracting the essence of the jcoffee,and separating it from the grain, than any now in use; and

It consists in the peculiar' construction of the strainer, whereby twoincreased straining-surfaces are produced, of unequal fineness, as willbe hereinafter more fully described. f

Figure l represents a sectional elevation of my improvernent, applied toa coi'eepot; and

Figure 2'represents a section ofthe same', taken on the linex :t ofiig. 1. r'

Similar` letters of reference indicate corresponding parts.

. AI represents .a sheet-metal vessel, preferably of round forni, andhaving a conical bottom, adapted. to titiuto the opening through the topof an ordinary tea or ooi'ee-pot.

v Withiuthe vessel A, I provide a perforated cone,

` B, having an opening in the top.

Within this cone, and extending through a hole in the bottom of thevessehA, I provide a perforated tube,'C,the said perforations beingsmaller than those Yinthe cone B.

The said tube is stopped at the top, and opened at the bottom; l p' Akey, E, may be passed through the lower end of the latter, below thebottom of the vessel A, to hold the cone B down to the said bottom, butso arranged Vthat it may be readily detached, from time to time,

for removing any of the finer grains that may pass through theperforations of the cone. u

The ground coiiee is placed in the vessel A, above the cone B, and thehot water-poured thereon,'in any required quantity, and allowed tovstand a Vshort time, for the water to filter through the coffee and theperforated cone' and tube, which it readily does', and passes into thepot below,.taking up, at the same time, the strength of the coi'ee, butleaving'the solidmatter.

yHaving thus described my invention,

I claim as new, and desireto securel by Letters Patent- Y The strainer,constructed as described, of the cone B, provided with coarseperforation's, and the finelypertbrated tube C, extending verticallythrough said cone, both arranged as described, and adapted for at'-tachment to the interior of the case A, iu the manner set forth, for thepurpose specified.

The above specification of my invention signed by me, this 29th day ofJanuary, 1869.
